During summertime I had an issue that the My Electric app shows yesterday’s use in KWh rather than today’s in the summary. This issue was reported here: EmonSD and time in Node Red? and the response is to set the timezone correctly in the user’s configuration. I made that change and it solved the problem for me.
However, I question whether this is the correct solution. That resolves the issue when the browser is in the same timezone as the server, but e.g. I travel often and when I do the problem would recur until my browser is back in Europe/London.
One option could be to always use the server’s timezone to determine how to divide up the days, since the energy usage (daytime vs. night) makes more sense in the server’s timezone anyway. Maybe there’s a better solution?
I’m mostly highlighting this as a feature request/call for ideas: my original problem has mostly been addressed for now.
